Webseveral spot welds are made close to each other. In such cases, previously made welds may affect the new weld and part of the current aimed for the new weld passes through the neighbouring welds. This effect is called shunting and is known to affect weld quality and reduce weld strength. A schematic of shunting is shown in Figure 1. WebThe E-Coat on the mating surfaces can be saved when using STRSW with the use of the Dent Fix Shunting Pliers (DF-SP360). Simply remove the coating from only the outside surfaces, position the shunting clamp at the spot weld site, and the spot weld is made at the adjacent site. The current chooses the path of least resistance when confronting ...
